6 Claims, 4 Drawing Figures GOLF SWING TRAINING ATTACHIVIENT Thisinvention generally relates to a golf swing training attachment, andmore particularly to an attachment which is fixed to the head of awooden club and adapted to enable a golfer to know most readily whetherhis club was swung with the face thereof facing accurately in thedirection of impact.

A first object of this invention is to provide a golf swing trainingattachment which is extremely light in weight scarcely affecting theweight of the club.

This is a very important factor for the reason that a golfer is unableto apprehend a perfect swing that is useful in the actual game if thetraining attachment greatly affects the weight of the club since no suchattachment is generally used when a game is actually played.

A second object of this invention is to provide a golf swing trainingattachment that is simple to handle and easy to attach to any woodenclub.

A third object of this invention is to provide a golf swing trainingattachment that is light in weight, compact in size and handy to carry.

A further object, which is the most important of all, is to provide agolf swing training attachment enabling the user to know that the clubwas swung precisely inside out by emitting a sound with an air stream.

These and other objects are accomplished by the parts, improvements,combinations and arrangements comprising the invention, a preferredembodiment of which is shown by way of example in the accompanyingdrawings, and herein described in detail. Various modifications andchanges in details of construction are comprehended within the scope ofthe appended claims. Of the drawings:

FIG. ii is a disassembled perspective view showing an embodiment of theattachment of this invention;

FIG. 2 is a sectional view of said attachment;

FIG. 3 is a vertically sectioned view of a whistle of said attachment;

FIG. 4 is a perspective view showing the state wherein said attachmenthas been attached to a golf club.

In the accompanying drawings, A designates a whistle, B designating afixing member having a suction disk.

Referring now to FIGS 1 and 2, the numeral 1 designates a cylindricalmember having an opening at each end thereof, the opening 2 being an airinlet. The numeral 7 designates a vibration plate consisting of thinmetal plate having resilience, 5 designating a tray for receiving thevibration plate 7. The whistle A is completed by placing said vibrationplate 7 on a flange 6 of the receiving tray 5 and inserting said plateand tray into the cylindrical member 1 through the left-side opening 2'thereof.

If the opening 2 of the cylindrical member 1 is formed slightly narrowerthan the backward opening 2' thereof, the vibration plate 7 and thereceiving tray 5 are free from the risk of projecting further forwardlyfrom the inlet 2 of the cylindrical member 1 when said vibration plate 7and receiving tray 5 are inserted thereinto.

Referring to FIGS. 2 and 3, a semicircular partition 12 is provided onthe interior wall of the central part of the cylindrical member 1, aprojecting ridge 13 being provided along said interior wall opposed tosaid retaining partition 12. The vibration plate 7 and the flange 6 ofthe receiving tray 5 are retained by the space between both ends of theprojecting ridge 13 and the retaining partition 12.

Referring again to FIG. 1, the fixing member B comprises a suction disk11 and a projecting member 9 for retaining the whistle A, saidprojecting member 9 having a penetration hole 8 through which to insertand secure the whistle A. If the fixing member B is manufactured withresilient material, such as nylon, polyethylene and the like, and thepenetration hole 8 is formed slightly narrower than the diameter of thecylindrical member 1, the fixing member B is capable of retaining thecylindrical member thereinside most effectively thereby obviating therisk of the whistle A being dislocated even by a violent movement.Moreover, the whistle member and the fixing member are easilyreplaceable if damaged. In addition thereto, the attachment of thisinvention which is made up of the aforementioned material is extremelylight in weight.

Furthermore, if a stopper 3 is provided slightly backwardly in relationto the air inlet of the cylindrical member 1 as shown in FIGS. 1 and 2,said stopper 3 enables not only to insert the whistle A into apredetermined position inside the hole 8 but also to prevent the risk ofthe whistle A being displaced by an impact of some object against thefront part of the attachment. Moreover, it will be convenient for theuser if an indicator 10, such as a line, an arrow and the like,designating the direction in which this attachment is to be fixed to theclub head is provided on the sucktion disk 11. Said fixing direction canbe made discernible also by providing a collar 4 around the air inlet 2of the cylindrical member 1.

FIG. 4 intends to show not only the state wherein the attachment of thisinvention has been fixed to the club head but also the principle of thefunction of said attachment. The attachment can be secured to the clubhead 14 by pressing the suction disk 11 against the upper surface ofsaid club head 14 in such manner that the whistle A is rectangular inrelation to the club face 15. The attachment of this invention can befixed by such a simple operation. The arrow in broken line in thedrawing shows a locus of the club head when the club is swung by agolfer. The arrows in solid line show the direction of the air stream.

When a golf club is swung, the speed of the club head increasesgradually from top swing to down swing, and it is most desirable thatsaid speed reaches the maximum at the moment of impact. Moreover, theprerequisite for a good swing is that the club face at the moment ofimpact is precisely rectangular in relation to the flight direction ofthe golf ball. Since the vibration plate 7 of the whistle A is adaptedto emit a smound when the club head reaches a desirable speed, theattachment of this invention enables the golfer to gain a clearcomprehension of the accurate swing by ascertaining whether saidattachment produced a sound when the club head was at the preciseposition of impact. Furthermore, the vibration plate is interchangeableaccording to the personal difference in the swing speed. I
